Okay so I'm interested in upgrading my PC, it's meh at the moment, can run Skyrim in very high but sometimes is unplayable in certain areas. League of legends is fine, constant 60 fps max graphics as to be expected on a game like LoL however some things bother me about my PC.

A major major problem would be every now and then especially when i'm trying to stream my monitor will cut off and sometimes will switch to a solid random color and switch off, or will sometimes get randomly colored vertical lines and switch off, however this is not a problem with my monitor as this is a brand new monitor and this also happened with my old monitor so any advice on that would be GREATLY appreciated.

Some smaller problems would be my FPS can sometimes be unsteady on a lot of games and can be choppy for instance on LoL. And streaming is very laggy.

I'd just like some advice on what to upgrade any help will be appreciated.

I'm going to guess the PSU is getting overloaded if everything is 100% causing your GPU to not get enough juice. If you are getting heavy FPS dips in certain areas then that would be a GPU problem, or the CPU not feeding enough info to the GPU.

Yea, the PSU seems to be an issue, you wouldn't happen to know the brand on the label for it would you? Easier to look up parts with model numbers. xD

That x2 is old and dated, could be one of the issues, but the fact you are getting graphical errors points to a fault GPU, driver, or PSU, which explains frame dips more than anything honestly, aside from the low powered CPU.

Ah ok, it's a Be Quiet! so a decent PSU. I still think there is a power issue though just because your temps aren't high at all.

If you are based in the US I suggest using Newegg.com - Computer Parts, Laptops, Electronics, HDTVs, Digital Cameras and More! for your PC purchases.
On that note, if you are going to upgrade to the FX then you will most likely need a new motherboard as well. Other than that, the parts seem ok for the most part.
Even though your CPU is dated, it is based on the newer Phenom 2 arch, and my 6000+ paired with a decent GPU still plays todays games. I really don't think your CPU is holding you back too much despite lack of GPU power.

As for the moderated posts, they just reverted this site back to VB 3.8 so they are working the bugs out. Moderated posts are required for newer members with less than 10 or 15 posts I believe. Same goes for the rep.
